` Application led June 5, 1912. Serial No.` 701,730.

Patented Jan. 7,1913.

To all whom z't'may concern.'

Be it known that I, LoUIs A. NEGRAvAL, a

v citizen of the United States, residing. at

Jersey City, in the county of Hudson and State'of New Jersey, haveinvented a certain new and useful Improvement in .Slides for Garment-Supporters, of which the following is a specification. i

' The invention p relates to friction slides used in connection withstrips or tapes of webbing in adjustable garters and analogous articles,and the object of the invention is to provide a slide of this classwhich will'perform its frictional holding functions successfully, may beeasily and economically manufactured from thin sheet metal with butlittle waste, and carries means formed integrally therewith for graspingthe end of the webbing reliably.

The invention consists in certain novel features and details ofconstructionby whichl the above objects are attained, to be hereinafterdescribed.

,The accompanying drawings form a part of this specification and show anapproved form of thev invention.

Figure 1 is a face view of the slide fin position upon a strip ofwebbing, and showing the outer face. Fig. 2 is a similar view of theslide alone. Fig. 3 is a corresponding view of the inner face, showingthe engaged end of the webbing. Fig. et is a face view of the slide asit appears at a stage of manufacture prior to bending to form-thegripping teeth and jaw. Fig. 5 is a transverse section 'of the slide ona larger scale, showing the position of the teeth and jaw after bendingbut before the insertion of the webbing-end. Fig. Q is a similar viewshowing the webbing-end 1n place and gripped by the teeth and jaw.

Similar letters of reference indicate the same parts in all thefigures.

The slide is shown as a thin metalframe of rectangular form having acentral bar `A and an opening or slot B C on each side thereof, throughwhich the tape or elastic webbing is passed as usual, but it will beunderstood that the contour of theslide is not essential and may bewidely varied.

A portion of the metal is removed to form the slot` C, the dies beingarranged to produce a smooth straight cut forming the inner l edge ofthe outer bar A2 and a serrated cut on the adjacent edge of the centralbar A, thus providing a series of sharp teeth D along the latter.

The slot B "s produced without removing the metal; a smooth cut isma'de'to form the inner edge of the outer bar A1 and is continued ashort distance inward at each end,

the inclosed material forming a ap, as indicated in Fig. 4, ready to bebent out of the plane of the bars to form the. jaw F. y

By the same dies thatformed the teeth D, or at a subsequent operation,the teeth are bent upward and backward toet-and at an angle slightlyacute to the plane of the bars, and the jaw F is similarly folded overon the same face to bring its free edge in proximity lto the line ofteeth, `as shown in Fig. 5. An

end of webbing Eis introduced between the teeth and jaw and the latterthen flattened upon the teeth by blows of a hammer or 1n alsuitablepress, to engage the end strongly.

The effect of the flattening operation is to curl the points of theteeth inwardly in position to resist the normal pull on the webbing andto lock the engaged end of the webbing by the overlap ofthe jaw Fthereon. Thus engaged the end is' securely held with the raw edgecompletely j aw, and sharp projecting edges of the metal are avoided.-

I claim A slide for the purpose set forth embodying in a single `elementa central lbar and outer bars with slots between them, a seriesconcealed beneath the of teeth formed on one edge of said central bar,and a jaw formed integrally on the opposite edge of said central barwith the material bent out of the plane of said bars to produce one ofsaid slots, said teeth extend.- ing toward the jaw and the jaw and teethextending in opposite directions toward each other and the jaw adaptedto overlap the teeth to grasp a webbing end between said jaw and teeth.

In testimony that I claim the invention above set forth I aiix mysignature, in presence of two witnesses.
